Victoria&Daniel will be in Germany on friday. England never comes to this kind of parties. And Felipe and Letizia are in the UK.

On Willem Alexander 40th Birthday party were present from England, The Earl and Countess of Wessex. I have seen pictures and some video footage of them
Maybe they will come if they don't have other engagements

If they were coming, I would imagine it would have been announced. These sorts of things and this type of crowd, you just don't pop in I would imagine.

This volcanic ash is so interesting to me. Maybe its because I live in on the East Coast of the US and we haven't had this type of issue (although hurricanes are no joke). Last year, I worked for a cruise company and we got a LOT of business when the airlines were canceling flights...people were trying to get from Point A to Point B via ship.
